S12II-430

When there is a need for a basic, efficient and reliable power supply for a stable office computer at a very affordable price, this unit is the first on the list. There is no doubt that the S12II-430 is all you need for a peace of mind. It has reliability built in by using high quality components assembled by Sea Sonic’s well-organized manufacturing process. Its advanced fan control system and 80 PLUS® Bronze certification are the tokens of energy savings. The power supply circuits and the system components are totally protected by Over Voltage-, Over Power- and Short Circuit Protection.

80 PLUS®Bronze

The 80 PLUS® Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill. The 80 PLUS® Bronze certification guarantees greater than 82 %, 85 % and 82 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. Sea Sonic’s Bronze Series is an economical choice with great performance and high built-in value.

Fluid Dyanamic Fan Bearing

High performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan.

How it works

When the fan shaft rotates, high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces. As the speed increases, so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth, effortless rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.
The following illustration depicts the main characteristics of the FDB fans:

S2FC

The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.

Ample +12 V Output

Enhanced +12 V current capability broadens utilization possibilities.

Solid Capacitor

Universal AC Input

Switch-mode power supplies can tolerate a wide range of power frequencies and voltages. The power supply is designed to automatically adjust to the inpout AC voltage, therefore it can safely be used anywhere in the world.
